Wards Airline Model 74BR-1055A

The schematic and parts list for the Wards Airline model 74BR−1055A portable radio appeared in the August 1947 issue of Radio News magazine. Electronics trade magazines often published this information for the benefit of hobbyists and even professional service shops who could not afford to buy official versions from the manufacturers or places like Sams Photofacts. Companies like RCA, Motorola, Airline, Delco, Westinghouse, General Electric, Admiral, etc., typically only provided service documentation to licensed sales and service establishments. Airline was the brand of radios and TVs sold by Montgomery Ward, just as Silvertone was the brand name of radios sold by Sears, Roebuck, & Co. Since there are still instances of these old radios around, as evidenced by this Airline model 74BR−1055A now listed on eBay, making schematics and parts lists - and sometimes even alignment and troubleshooting data - is useful to someone. Note the unusual mounting of the electronics chassis upside-down at the top of the case. I wonder if that configuration caused heat dissipation issues since the hot air from the vacuum tubes would tend to convect upwards.

Radio Service Data Sheets

These schematics, tuning instructions, and other data are reproduced from my collection of vintage radio and electronics magazines. As back in the era, similar schematic and service info was available for purchase from sources such as SAMS Photofacts, but these printings were a no-cost bonus for readers. There are 227 Radio Service Data Sheets as of December 28, 2020.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
